The frame on which the bindingdevices are mounted consists of an oblong rectangular frame having the sill-bars A A', end bars, B B', upright posts CC', andthe upper or cross bars, D D. The frame thus constructed is mounted upon the projecting frame-bars adjacent to the carrier, as described in the application of even date herewith, and-as shown in Fig. l of the drawings in this application, being mounted thereon in such amanner as to have an endwise movement to adjust the binding devices to dilerent lengths of grain in a manner hereinafter explained.

In bearings a a', one located centrally and the other at the rear end of the sill-bar A, is

mounted a rock-shaft, E, having secured at its inner end a trip arm or finger, E', and `at its othera crank-arm, E, which in turn is connected with a perpendicularly-arranged arm or lever, E3, having its connected end slotted, as shown. The lever E3 is shown mounted in a guideway, E, secured to a cross arm or brace, C, extending between the posts C C'. This arm E3. is connected at its upper end through a link, E5, with the arm of a rock-shaft, G, mounted in bearings e e upon the cross-bar D of the frame above and parallel with the rockshaft E, and has also pivoted to it about midway of its length a pawl, E, which is in turn pivoted to the arm or brace C, with its free end bent, as shown, to engage a cam-face, H", formedlupon the hub of the binder-mechanism gear-wheel H, which cam is formed by cutting away a portion of said hub and for a purpose hereinafter explained.

The pawl Es has connected to it a spiral spring, e, lwhich at its upper end is connected with a screw-threaded shaft, e7, mounted in a bearing, e, secured to the bar C4, and having mounted thereon a thumb-nut or handle, E, by whichthe tension of the spring upon the pawl E6 may bc regulated, for thepurpose hereinafter explained.

A shaft, I, is mounted at one end in bearings connected to the post C and at the other1 in an arm or support, C5, extending between the upper cross-bars, D D,and parallel with the shafts E and G, being located about midway between the same. This shaft has keyedupon one end a sprocket-wheel, 1', having an enlarged hub or disk formed therewith, and from the outer face of which disk project friction-sleeved lugs I, and adjacent to this wheel the shaft has loosely mounted upon it a pinion, I3, also having a hub or diskformed tl|ereon,and on which disk is pivoted ay rocking spring-pawl, I, having arms iii?, from one of which, i, projects a friction-sleeved lug hereinafter referred to. Upon the opposite end of this shaft is loosely mounted a pinion, J, having a disk or plate, J', secured thereto, carrying upon its outer face a rocking spring-pawl. J2, formed in a similar manner to the pawl I. The shaft has formed in it upon onel side of the frame C5 a crank portion, to which is connected one of the packing-arms, the other being connected t0 the outer end of the shaft through an arm, J", rigidly connected centrally of its length to said shaft I. This arm J* carries upon each end upon the face adjacent to the disk frictionsleeved lugs J5 to be engaged by the arm ofthe pawl J2,'carrying the sleeved lug, in a manner hereinafter explained.

Upon the frame G5 is pivotally supported a bifurcated or forked arm, G', with its depending arms overhanging the pawl J2, and provided with inwardly-projecting lugs h h to engage the pawl-arm.

The upper end ofthe arm G is provided Vwith an extended lng or e'ar, g, which is connected with a crank-arm extending from the rock-shaft G through a link, g. Astud-shaft,

G2, has mounted upon ita pinion, G3, to engage the pinion J, and the pinion G3 has projecting from it a lug or ear, g", which is connected through a link or arm, g3, with a pivoted separatingarnnG, mounted in a projecting portion of the arm or support C5,over hanging the carrier. The separating-arm G has extending .from its front face an arm or lug, g?, to which is connected a guiding and depressing arm, gfgwhich curves from its point of connection with the separating-arm first downward and thence upward and forward above the'carrier, and has its forward end forked or slotted, as shown at y, to engage a guide-rod, gw, xed to any suitable point on the frame of the machine. This guiding and depressing arm,being connected with the separating-arm, operates simultaneously therewith and in suchmanner that when the separating-arm is forced downward and outward toward the carrier to divide and hold the incoming grain from that accumulated to form the bundle the guiding-arm will be raised to afford space for the grain brought by the carrier against the separating-arm but when the separating-arm is raised to permit the grain to pass to the bi riding-receptacle the guiding and depressing arm will' act-to press that upon the apron downward and backward and into posi-` tion to be acted upon by the packers, the

IIO

end of the guiding and depressing arm being held and controlledin its movement at its for-l ward end by the guide-rod glo.

A lever-arm,K,pivoted in bearings secured to the underside ofthe 'framebar D near the post C, extends out therefrom and rests upon the 1ink'g2, and hasV itsother end connected through an arm o r link, K, to one arm of an angular frame, K2, straddling thelever E3 below thepoint of connection therewith Vof the pawl E6, and having apivotal connection, K4, inthe arm or brace C4. The other or rear arm ofithis frame extends parallel with the front arin and is provided with a lugior projection, K5, to engage the armi of the rocking pawl I4. The lever-arm K has `connected to itbetween its pivotal point and its point `of ,connection with the arm( or"link K a f spiral spring, Kwhich is'inturn connected withthe -r frame-bar D, serving to hold the lug on the frame K2' in engagementwith the arm of the 'pawl I4, andalsoits free end presseddown upon thelink g3 of the separating-arm.

On a stud-axle projecting fromv 'theinner arm G', which releases the pawl J2 from engagement with the lug h, when the stud-pin-`1 ion of the pawl willbe engaged'b'y one of the,

sleeved lugsJ5 ony the arm`J4 to clutch the pinion to the arm J4, andconsequentlybe 'revolved thereby. When the pinion has made a half-revolution, the pawl will be'engaged by thev lug h', which hasfby the .rocking of the .forked arm to release the pawl on one side been brought into proper position to engage it on the other to throw the pawl outof enl gagement with the sleeved lug and unclutch the pinion from the arm.

of the pinion J it communicates motion tothe Iny the movement pinion' G4,which' in its revolution, acting through its connectingarm, forces the sepa-v rating-arm outward to catch the incoming grain' and divide it from that -acc'umulatedto form the bundle. `As the pinion, G3 revolves,

it raises the link g, which actsA to raise the lever-arm K, overcoming the tension of the spring, and through the connection of theile;

' and stud-pin t3 and communicate mo'tion'to verarm .K'with the frame K2 `to rock said frame upon the pivot K4, releasing the pawl 14 on the pinion l from engagement-with 'the lug', apd cause the sprocket wheelv to be clutched' therewith through the sleeved lugs `l2 the gear-wheel on the binder-shaft.v Before the tripping mechanism isbroughtinto action thenose ofthe pawl E6 rests on the cut-away ornarrowest portion of the cam H on thehub ver E3 is drawn ydown by the action of the rock-' v, shaft E thereon and simultaneously with the of the gear-wheel H; butwhen thearm or lee i rocking of the shaft G it also raises the pawl Eiout of engagement with the camzH, and as the wheel -is revolved through the sprocket?` wheel I', pinion 12, and intermediatezpiniom E", the enlarged-portion of theehub is causedY to engage'thepawl and hold it in the position to which it hasbeen raisedby thetrip-arm and against the tension of the spring e, and also the arm or lever Eff in the position towhich ithas beenlowered. The'slot l'in the endof the arm or lever E3, whenit isinthis position and free from the tension of the spring, permits thearm p connecting the trip-arm withv the lever E3 .to

have av free movement within the i limits-of the slot yand allow a'conse'quent movement of the trip-ann'for a purpose hereinafter,v

explained. When the'gear-'wheel hasmade nearly a complete revolution and the pawl-E6 l reaches the cut-away portion ofthe hub, it is'y forced into engagementtherewith by the spring e6, raising the'arm E3, which rocks the shaft G and through y it lswings the` Vforked-- arm G', causingsaid forked arm to resume its normal position, which movement releases the pawl J2 fromengagement'withithe lug h', and to'be again engaged bythe sleeved lug Jion the arm J4 andfconiplete the revolution of the pimien, which raises theseparating-arm outofl theway of the' grain intoits originall position,

which movement releasesv lthe arm ,K ,andv by the action of the springK3 'upon itsfoppositeroo end causes it to raise the frame K2 'and bring the lug Kiinto position to engage the pawl 14,

`throwing' the pinion out o fclutch with sprocketwheel and bringing the wheel H to rest.f l]je sprocket-wheel, being keyed yto the shaft I,

continues to revolve ,to operate the packing arms, fin a'nianner that willbe yreadily understood. V The packing-arms, as before stated, are arrangedupon each side ofthe arm or support C5 and of vthe separatingarm G4, and operate. insuch a manner ythat whentheseparatingz arm lias been thrown "down to catch and forcey the'incoming grain backward toward the carf lrier, and before the needle begins 4t'oyact, the

packers, continuing to revolve, will .take any l grain left upon the rear edgeof the separatingarm andknotting mechanism and'carry itto that accumulated to kform the bundle, "ands thereby leave a clean'space. for the needlel to ,work through, and consequently prevent any clogging or the carrying of any grainybyathe needle through the, slot into the shield:I l 1 The knotter-mechanisni frameLis supported at its vtop from the .cross-bar D ,and ,is pro-v videdjwith hubs or-bearings L', th rough which the operating-shaft L2 passes, The frame con? v sists of the two arms L21?, havi'ngbent arms or supports Z Z', extending from the lower side. of the hubs L', through which the end ofA the shieldv L4 is con nectedtherewith, the forward end of the shield being connected'with the un-V der face ofthe supportC, and is'pnovidedv with longitudinal slots to permit the movement ofthe separating-arms, packers, and needle-arm through the same. The space between the inner faces of the hubs L is made of such width as to closely tit the hub of knotter-cam and gear-wheel M, and the wheel M is connected to the shaft L12 by means of a feather or key engaging a longitudinal groove or keyseat formed in the shaft, which manner of connecting said wheel, while permitting it to be readily connected or disconnected from its shaft, firmly holds it in place. and prevents it from wabbling or in any manner becoming disconnected from the parts it operates.

The hub of the arm L2 has depending from it, cast or otherwise secured thereto, a knotter-supporting frame, M, having side arms, m, and connecting cross-arms m', the cross-arms serving as bearings for the knotter-shaft, and

the frame is braced by an arm, Z3, extending from the lower cross-arm to the support i.

The knotter consists of a central sleeve, M, with which the fixed lower jaw, m, is formed, which sleeve fits and is adapted to turn in the bearings m m. Upon this sleeve and keyed thereto is mounted a pinion, m3, by which the kuotter is revolved. The upper jaw, m4, is pivoted at its heel end within the fixed jaw and extends out to the point thereof, and hasv connected to it between its point and pivot a rod, m5, mounted and moving in the sleeve M2. This shaft has mounted upon its upper end a head or-disk, m, through which the rod is reciprocated in the-sleeve to open and close the pivoted jaw by rocking it on its pivoted heel end.

The knotting-mechanism cam and gear` wheel M is provided with an inwardly-projecting rim, M3, and a series of teeth, M4, extending therefrom and through the rim, and the hub is squared or cut away, as shown at mi, and between 'the cut-away portion of the hub and teeth is formed a wedge-shaped cam, m8, which teeth, hub, and cam operate to revolve and open and close the pivoted jaw in the following manner: As the wheel is revolved, the teeth M4 engage the pinion to revolve the same, and after the pinion has made a part of itsrevolution the wedge-shaped cam m8 moves beneath the head on disk m, causing said head to ride on the inclined free end of the cam, and consequently reciprocates the shaft and opens the jaw to receive the cord, the squared or cutaway portion of the hub permitting such movement. After the cord has passed 4between the jaws, the head or disk is released from the cam, and by the engagement of the solid or curved portion of thehub with the upper face of the disk the jaw is closed.

The cam or gear wheel M is provided on its rear side with a circular cam-track having a depressed portion, n', formed on a circle of less diameter than the raised portion n, and connected by inclined portions n?, and is also provided within the cam-track with cam-faces n3, said cams operating in a manner hereinafter described.

Pivoted to the arm L3 is a lever, O, having its lower end extending downto the upper face of the shield, and has connected to said lower end a bar, O', extending at right angles therefrom and having its outer end engaged by and moving in a slot formed in the lower end of the support Z.

Thelever O has an arm, O, projecting therefrom, with a friction-wheel at its outer end, which arm extends out and into-engagement with the cam-face nl, and-by the action of the cam' thereon swings the lever on its pivotal connection. Upon one side of the bar O is rigidly secured the knife O2, and upon the opposite side is secured the combined cord guide and stripper O. The combined cord guide and stripper is made in angle form and provided with a central slot, O, extending into and in line with the knotter, the two arms formed by slotting the same being curved outwardly therefrom to prevent the cord from being accidentally displaced.

The gripping devices and the arms and links by which the same are operated are mounted in a frame, l? P', having a pivotal connection at its upper end-in bearings p, formed in the frame L and projecting therefrom4 above and parallel with the bearings L. The two arms of the gripper-frame are connected by a crossrod, p', and are provided with three depending arms, p p? p4, below the cross-rod p. The central arm, p3, forms a support for the gripper-disk R, pawl-arm R', and pawl and ratchet Rf; the side arm, pi, a support for. the grippershoe R3, and the arm p4 a guide for the link R, connecting the lever O with the pawl-arm R. The gripper-shoe Ra is pivoted to the arm pl, and is held in proper relation with a yielding pressure over the gripper-disk by a spring, R5, to permit the shoe to yield for the passage of knots or uneven surfaces in the cord. The link R, which intermittently operates the gripper-disk, is connected to the lever O through a curved guide-arm, O5, rigidly iixed to the lever, which manner of connecting the same, while permitting the lever to be swung to reciprocate the bar O and move the knife and cord guide and stripper, and also oscillate the pawl-arm R to intermittently revolve the gripper, permits the frameP to be swung to and from the knotter, for a purpose hereinafter explained. A dog, R, is pivoted to the arm p* and has one end arranged to engage the teeth of the ratchet Rz and its heel end connected through a spiral spring with the arm P. A stud-pin, S, provided with a friction-wheel, extends from the framep in position to be engaged by thev camtrack an a, and by its engagement with the portion n causes the frame, with the parts mounted thereon,to be forced or swung bodily from the knotter, and the depressed portion n permitting it to be drawn. toward the knotter by the action of ythe cord thereon during the operation of tying.

Upon each side of the knotting-mechanism frame upon the shaft L2 are mounted the eject- ICO IlfI

.0r-arms Tfr", withal@ hub o f the am Tjah-utting. against the hub L', and which arm has the `arm O, and by means of which the arm is swung inward 4toward the knotterto recipro-AV cate theknifetosever theicord and move the cord-guide to strip the knot, Yand act simulthe needle being constructed in the usualmanf ner, except that it is'provided with a projecting lug, V2, arranged thereon to engage the trip-arm, and after the same has been released,- after throwing the separator and binding mechanism into action, as before described,

and by itsV action thereon to force. the arm up against the bundle'and cause itto act "as a compressorarm, the slot formed in th'e end of the lever E3, before referred to, ypermitting it to have suticient movement for this purpose.. 'The needle-shaft is .rocked by means of a'pitman, V3, connected vtothe wristpin on the wheel H, before referredto, the pitman being connected to said shaft through. a crankarm, V. f Y. A tension andv rake-up arm, W, having a guidingeye,W. formed inone end, is mounted i on a stud-shaftfWf, and in position" to he en# gaged bya lug formed on the needleshaft, said take-up arm being forced down by means of a coiled spring/having one end Yconnected with the studshaft and the other end with a pin projecting from the arm W. At the forward end of the arm W is mounted a rocking bellcrank arm, X, having its forward end, X', made to curve around the end of the arm W, and having its lother arm connectedto the frame above the stud-shaft W2 through a rigid arm,X2.

The arm in which the guiding-eyes are formed, through which the cord passes from the twine-box to the needle,is.made in U form, ywith an eye in ...each end, with a depending larm projecting from one of its ends to connect it with the frame, the arrangementof the partsA being such .that the end of the tension and take-,up'arm shalll lie between the ends of the Ushaped arm when in its position ofr rest, .with the cordfpassing first through one eye, thence through the eyein the take-up arm W, and thence through the other eye to the needle. Asl the needle ismoved up to take the ,cord to thek gripper, the tension and take-up arm is acted upon and'raised, drawing upon ,the cord, andthe point of ther'ocking arm X will, be thrown downwardj by its arm and ,causedtopress yupon and tighten the cord in a manner and for a purpose that will be read,.-

.ilynnderstood The arm E3, throughxwhich the trip mechan is mis actuated,has' mounted up on its upper endj -ra handle,y l, within convenient reach of 'thel driver,y and .byfpressin'g uPQn whichhe is ,en`

'The ,operation andtime andmovement'of the several parts, briefly stated, are asQfollowsg" The grain, being brought in bythe"cafrrier'to f within. reach of the packing-arms," is'jtak'en thereby and forced upon and over the triparm E against the rear compressor. When sucient grain has accumulated to form a.v

bundle, the size being predetermined in aecordance with the condition of the grain, the tension on the trip beingset in accordance therewith, the trip-arm is pressed down, and, acting through the rock-shafts, as before described, throws the separating-arm downward to divide the incoming grain from that accumulated to form the bundle. After the separating-arm has been thrown entirely down, and before the needle commences its movement,the packing-arms,continuing toact, pick up any grain left in rear of the separatingarm and carry it to that accumulated to form the bundle. The needle then commences its upward movement to carry the cord around the bundle and into the gripper. At this time the cam n3, acting on the arm O* of the lever '0, swings said lever backward, moving the knife out of the way of the cord and carrying the cord guide and stripper hack, forcing the cord close up to the shank of the knotter, and through the link R* and the pawl-arm R revolves the gripper-wheel the distance of one notch to grip the cord brought forward bythe needle. The knotter now commences its revolution to wrap the fcord around the salne. At this point the depressed portion of the camtrack is brought opposite the friction-wheel S, projecting from the arm p of the frame, and as the kuotter draws upon the cord the frame swings inward, moving on the curved arm O5, and is drawn close up to the knetter, giving the knotter suicient cord to form the loop. After the cord has been looped around the knotter, the wedge-shaped cam m moves beneath the head or disk on to open and the solid curved portion of the hub to engage the upper side to close the pivoted jaw, as before described. The ej ector-arms at this point, acting on the bundle to eject the same, have reached the point at which the friction-wheel T2 on the arm T begins to act on the lever Oto force the knife forward to sever the cord, and the combined guide and stripper to strip the knot, at the same time to swing the link R* and the pawl-arm R to permit the paWl to engage the next tooth to revolve the gripper at the next operation.l As the needle recedes the enlarged portion n of the track engages the friction-wheel S and forces the gripper-frame back to its normal position, by which action suftlcient'cord is drawn from thetwine-box to provide sufficient slack for the next bundle, for the purpose before stated.

Parts of the machine not herein particularly described may be'constructed in any usual or preferred way, and the binding mechanism may be mounted upon and used with a harvester which presents the grain thereto in a different manner than that described.

The matter herein described relating tothe single arm or lever for operating the cord guide, gripper', stripper, and knife is made `the subject of a separate application.

Having now described my invention, I claim- 1. The combination of a separator-arm for dividing the grain, mounted so as to oscillate a trip-arm, and mechanism, substantially as described, for connecting said arms, as set forth,whereby the trip is caused to automatically and positively control the movements of t-he separator by the grain accumulated to.

form the bundle and cause it to hold the incoming grain during the binding operation.

2. The combination of the carrier, a binding mechanism, packers, and aseparating-arm operating in a reverse direction to the packers, and a trip mechanism for controlling the separating-arm, substantially as described, whereby the separating-arm is caused to act upon the incoming grain upon the carrier and force it back and out of the way ofthe packers, as and for the purpose set forth.

3. An automatic trip for grain-binders acted upon and controlled by the separating-arm, in combination with means to be controlled by the driver in his seat on the machine for operating the trip at will, substantially as described.

4. The combination of an automatically-operated separator and an automatically-operated trip, with means to be controlled by the driver for throwing the same into action at will, substantially as described.

5. An automatic trip for grain-binders acted upon and controlled positively by the separating-arm, substantially as described, whereby the grain to form the bundle is separated from the incoming grain before the binding devices are brought into action, as and for the purpose set forth.

6. The combination of the horizontally-arranged carrier, a trip-arm located in the path of the grain, aseparating-arm actuated bythe trip-arm, and a binder-mechanism trip actuated by the separating-arm, substantially as and for the purpose set forth.

7. The combination,with theintermittentlyrotating pinion for imparting motion to the separator, of the bifurcated pivoted rocking arm operated by the trip-arm to .rock said arm and cause it to alternately disengage and engage the clutch of the pinion to throw the same into and out of action, substantially as and for the purpose set forth. v

8. The combination of the fixed jaw, the pivoted A jaw, the rod or shaft. provided with the disk or head, and a revolving drive-wheel provided with cams to engage the head to reciprocate the shaft and positively open and close the jaw, substantially as described.

' 9. The combination of the swinging frame carrying the gripper, the reciprocating combined cord guide and stripper, a knife, the arm or lever for reciprocating the cord guide, stripper, and knife, an arm connected with the knife-arm and forming a guide for and connection between the gripper-frame, cord guide, stripper, and knife, and a revolving drive- Wheel provided with cams for reciprocating I'IO thecord 4"guide, stripper, and knife, intermittently operating the gripper, and swinging the gripper-framefrorn,the knetter, substantially -as and for the purpose set forth.

10. rI he combination ofthe revoluble knotter-shaft, the'combined cord guide and stripper, a knife" having a fixed relation to the cord guide and stripper, the cam and rack wheel for revolving the knetter and moving the knife and guide in one direction, andthe revolving ejector-arm forv reciprocating the cord guide and knife in the opposite direction to sever the cord and strip the -knot from. the knotter,

substantially as and for'the purpose set forth.

11.v The combination of'the reciprocating knife, the gripper, and means, substantially as described, for connecting said gripper` and knife, asset forth, whereby the knife is recip-' rocated and lthe gripper-frame swung bodily.

from the knot-ter and intermittently rotated by the knifereciprocating mechanism.

12. T he combinationof .the cord guide'and stripper, a knife, a cord-gripper, and an arm or lever for operating the same, substantiallyV as described,whereby the cord guide and stripper is reciprocated andthe gripper swung to and from the knotter Vand `intermittently re volved, for the purposes set forth.

13. The reciprocating cord guide and stri e per, in combination with an ejector-arm acting on the stripper to cause the same to strip the knot simultaneously with its action in ejecting the bundle, as and for the purpose set forth. f Y 14. Thecombination of the cord guide and` stripper, a knife, and an armor lever for op erating said parts, having a swinging movement imparted thereto by the revolving geary andcam wheel and the revolving ejector-arm,

substantially as described. 1

Y15. The slotted frame for carrying the tying devices, provided with bearings for the driving-shaft upon each side ofthe cam and gear A wheel, in combination -with the drivingshaft v provided with the key seat or slot .to engage` the feat-her inthe gear-wheel, substantially as and for thepurpose set forth.

16. The combination of the guiding and depressing arm with the Vseparating-arm, operating and timed iin their movements substan. tially-as and for the purpose .set forth.

17. The combination of the tension andtakel v up arm, the rockingy arm pivoted to the end of the take-up arm and connected'to the frame bya link operating substantially as described, and the needle-shaft provided with the camor projection to' engage the arm of the take-up ssJ andoperate the same,- andthroughrt the rook- A ing arm, as and for the purpose set forth.'`
